I've just recently had to rebuild my HTPC with a newer version of Windows
7. I have been using an ATi HD5450 card in my setup for over a year now with no problems.
However, with this new build I've put on, I am now not getting any signal to my receiver from my HTPC. However, as soon as I turn on my TV, I get a signal to the receiver!! So I can get audio but always have to have the TV on, which is not how I remember it working before.
I am no nearer to finding out why all of a sudden there is no signal from my PC to receiver. I have carried out a few tests that Yamaha have advised me to as I thought the issue was with the receiver but it looks like a problem with the Windows 7 and codecs.
I've just checked and I am running the latest drivers for my card as well.
Hope someone can help! Thanks
